Audio Improvements

New:

• Added stereo spatialization fix
  • fixes resource pack and mod audio that incorrectly uses stereo files for in-world sounds by converting them to mono, so the sound engine can then correctly position it instead of always playing directly at the listener
  • enabled by default

Fixes:

• Changed how music disc sounds get detected, should now detect most music discs from other mods
• Fixed mono sounds being played behind the listener instead of in front, which may have caused some volume problems
